Description

A RAPID TOOL COUPLING DEVICE FOR DIGGER TOOLS
Field of Invention:
The present invention relates to a device useful for digger tools and the like.

Backctround to the Invention:
Numerous manufacturers of diggers and digger tools exist on the market today.

Also numerous are the different types of attachments, which are generally dimensioned and configured so that only tools having complementary attachments can be hooked up to them. This constitutes a serious limitation to tool use, as it is not easy to obtain a full range of tools, buckets or otherwise, for a single digger.

In view of the above-noted shortcomings, the present invention seeks to provide a rapid coupling device which overcomes the limitations of the prior art with a simple solution.

Summary of the Invention:
The present invention provides a rapid coupling device which overcomes the limitations of the prior art with a simple solution. Specifically, though not exclusively, the present.
invention is useful for all tools, in particular buckets, which are hooked up using two parallel pivots predisposed on the bucket, which are used for hooking up to a rapid-coupling device provided on the end of the digger manoeuvring arm.

In a first aspect, the present invention provides a rapid tool coupling device for digger tools, in which a tool is provided with two pivots operating as means for hooking-up, comprising a body provided with devices for blocking, having mobile hooks which are actuated to achieve stable removable couplings with at least one of the two pivots; and at least one plurality of first supports and at least one second support, which are predisposed to couple with a corresponding plurality of pairs of the two pivots, which pairs comprise a first pivot and a second pivot, and which can be removably fixed to the body.

In a broad embodiment, the invention therefore seeks to provide a rapid tool coupling device for releasably securing to a working machine a digging tool selected from a plurality of available digging tools, wherein each digging tool comprises a pin connection unit comprising a first pin and a second pin, and at least some of the respective pin connection units of the available digging tools being different in relation to at least one of their pin size and their configuration, the rapid tool coupling device comprising:
a body operatively coupled to the working machine;
a plurality of first supports and at least one second support being constructed and arranged to engage selected pins of the respective pin connection units and being removably fixable to said body;
displaceable hooks each constructed and arranged to engage selected ones of said first and second pins;
wherein the first and second supports are selected to correspond with the pin size and configuration of the pin connection unit of the selected digging tool.
2 Preferably, the device further comprises a plurality of second supports constructed and arranged to correspond with the pin size and configuration of the pin connection units of the available digging tools.
Preferably, each first support and each second support is provided with a seating for contactingly housing the first and second pin respectively of the pin connection unit of a selected digging tool.
Preferably, the first supports and the second supports are constructed and arranged to be removably fixable to the body in predetermined positions by removable constraints, and more preferably, first reference points are provided on the body and the removable constraints use the same reference points for each of the first supports.

Preferably, second reference points are also provided on the body and the removable constraints use the same reference points for each of the second supports.

Preferably, each of the first reference points and the second reference points comprise holes constructed and arranged to receive bolt connections.
Brief Description of the Drawings:
Further characteristics and advantages of the present invention will be provided in the detailed description that follows, illustrated by way of example and not to be considered limited to the accompanying figures of the drawings, in which:
3 Figure 1 is a partially-sectioned schematic side view according to line III-III of Figure 3;
Figure 2 is a side view of a detail shown Figure 1;

Figure 3 is a schematic side view from the left of the detail shown in Figure 2;
Figure 4 is an exploded side view of the detail shown in Figure 2.

Detailed Description:
The invention will be described for the purposes of illustration only in connection with certain embodiments; however, it is to be understood that other objects and advantages of the present invention will be made apparent by the following description of the drawings according to the present invention. While the preferred embodiment is disclosed, this is not intended to be limiting. Rather, the general principles set forth herein are considered to be merely illustrative of the scope of the present invention and it is further understood that numerous changes may be made without straying from the scope of the present invention.
With reference to the drawings, Figure 1 to 4 illustrates a body 1 of a rapid coupling device for digger tools, of the type in which the tool 7 is provided with a first pivot shown as pin 3 and a second pivot shown as pin 4. The first pin 3 and the second pin 4 together constitute means by which the tool will be hooked up. The body 1 is provided with blocking devices comprising mobile hooks 2 which achieve stable but removable couplings with at least one of the two pins 3 and 4, and especially with the second pin 4.
4 The hooking-up is achieved by coupling the pins 3 and 4 in special coupling seatings 50 and 60 especially afforded in first supports 5 and second supports 6 which are removably fixed on the body 1. Each body 1 is predisposed to receive a pair of first supports 5 and a pair of second supports 6. The supports of each pair are positioned in such a way that the surfaces of the seatings 50 and 60 are aligned to couple respectively with the first pins 3 and the second pins 4. The first supports 5 and the second supports 6 are mounted easily and removably on the body 1, and can be constrained thereon in predetermined positions.
Furthermore, for each tool 7, i.e. for each hooking-up system constituted by a first pin 3 and a second pin 4, a set formed by a pair of first supports 5 and a pair of second supports 6 is provided. Thus, by mounting the right supports 5 and 6 on the body 1, the desired tool can be fixed thereon.

It is not certain that in each case the above-described conditions will arise. It is possible that even with a plurality of different tools 7, it will be necessary to have a corresponding number of first supports 5 and only one second support 6 - or vice versa. In this embodiment, the first pins 3 (or second pins 4) of a plurality of tools 7 are not very different in type one from another. The pins 3 and 4 can be coupled in a single seating 50 (or 60) of a first support 5 (or second support 6), the same seating being suitable for all of the tools 7, for situations where the geometrical and dimensional difference in the attachment is present only in the seatings 60 (or 50) of the second supports 6 (or first supports 5).

More generally, there is a plurality of first supports 5 which
5 corresponds to a plurality of second supports 6. These supports 5 and 6 are predisposed to couple with a corresponding plurality of the first pins 3 and the second pins 4, and can in all cases be removably fixed to the body 1. The stability of the couplings is ensured by the fact that a single pair, formed by a first pin 3 and a second pin 4 on a single tool 7, is coupled with another pair constituted by first supports 5 and second supports 6.

The relative linkage between the first supports 5 and the body 1 is removable and uses a common reference on the body for all the first supports S. The relative linkage between the second supports 6 and the body 1 is removable and uses the same references on the body for all the second supports 6.

In particular, the references are formed by holes 11 made on the body 1 for allowing any first support 5 to be bolted thereon, and by other holes 12, also made on the body 1 for allowing any second support 6 to be bolted thereon.

The adaptation of the tool attachment to a specific tool 7 is made easy by making the attachment itself as a modular structure which comprises a body 1, provided with mobile hooks 2 which in the illustrated embodiment are so moved by a pneumatic cylinder 8, and a double plurality of pairs of first supports 5 and second supports 6 which are easily mountable on, and dismountable from, the body 1.

A special combination of first supports 5 and second supports 6 corresponds to each tool. When mounted on the body 1, by using the predetermined references, a rapid attachment can simply be
6 obtained simply, which corresponds to the particular coupling dimensions of the single tool.

It should be understood that the preferred embodiments mentioned here are merely illustrative of the present invention. Numerous variations in design and use of the present invention may be contemplated in view of the following claims without straying from the intended scope and field of invention herein disclosed.
